Introduction
The DG501C controller
•
allows the complete automatic control and management of the air-conditioning plant
type chosen among the various applications (see, further for a list) configured and
existing in the controller. In order to enable the required application, it is sufficient to
carry out the controller electrical connections according to the relevant scheme and to
follow the instructions in the present manual.
•
once the controller has been installed and connected, it is started up by simply switching
on power supply. No configuration intervention on the part of the user is needed. The
only necessary operations, to be carried out from the display, are to set time and time
schedules. In any case, it will be possible, using the display, to supervise and correct the
origin values of the variables.
Consider that:
•
no particular instrument, even the PC, is required to install and use DG500 .
•
all operations are carried out through the display in a simple and user-friendly
way.
Start-up
Once the application type, from 1 to 9, has been chosen, and the relevant connections have
been carried out, stick the label (supplied in the package) which identifies the scheme
number. This has the purpose to make it evident for future interventions on the plant.
- Verify that the isolating strap, protecting the battery, has been removed, as described in
the paragraph LCD panel mounting at page 7
- Switch on power supply.
- After some moment, on the display the date and time appear. Press
Esc.
- Using the navigation button, select the menu Set Clock , set the current date and time and
confirm using the Enter button.
-
Press Esc . to go back to the start menu and verify the correct date and time are set.
At this time, if the pre-set parameters related to time programming (i.e. permanent operation)
and to the set value of the variables satisfy the plant requirements, the
controller becomes
immediately operating .
In the frequent case a customised time and daily schedule is required, scroll the menu up to
the time to be modified (primary air or fan coil) and enter the required data using the
procedure described below.
